I saw this idea in some old camping book or maybe the scout manual from the 50’s. If you can find three old strap hinges like used to be on old shed doors, or old wooden gates, they can be fastened together at the tips to make a handy cooking platform. They need to be six inches from tip to pivot, so that there’s room under the arrangement to build your small fire, as shown below. This will accomodate most skillets and pots. If you have compact cooking gear, you might get by with smaller hinges.
